On data=journal mode hangs. writeback and ordered run fine. After several runs (hangs), I was able to get some sysrq output to the serial console. kernel config: http://oss.oracle.com/~rdunlap/configs/config-2620-rc4-hangs message log: http://oss.oracle.com/~rdunlap/logs/fsx-capture.txt Can anyone see what fsx-linux is waiting on there?
